Screw caps are used to cover the screw heads, providing a finished look for your vents. There are 3 colours to choose from - matte white, matte black and silver.
Each pack contains 4 screw caps in your colour of choice, and 4 washers for attaching the caps to the screws*. To use the screw caps, simply insert the screw into the washer, and then screw it into the vent. The cap is then clipped onto the washer to cover the screw.
*screws supplied with vent, and are not included in the screw caps pack.
